On October 12, 2026, Sinfonia Varsovia and WARBUD signed a contract for the second phase of the project at 272 Grochowska Street. Initial work will begin later this year, and the schedule expects construction to be completed in 42 months.
At the heart of Sinfonia Varsovia’s headquarters at 272 Grochowska Street is Poland’s largest concert hall, with 1 877 seats. Designed by Atelier Thomas Pucher in collaboration with acousticians from Müller-BBM and Eckhard Kahle Acoustics, it will combine the features of two types of concert halls: the shoe box, with a rectangular layout, and the vineyard, in which the audience surrounds the stage. The usable floor area of the hall will be nearly 22 500 m², creating ideal conditions for performing symphonic music. The projected reverberation time will be approximately 2.0–2.3 seconds at mid-range frequencies, and a slight increase in reverberation time for low frequencies will help achieve a warmer sound.
The spacious foyer of the concert hall will be open to visitors – not only during concerts, but for most of the day. Thanks to the use of glass walls, visitors will be able to freely view the interior of the concert hall while strolling through the foyer. Thomas Pucher, the architect behind Sinfonia Varsovia’s headquarters, designed it so that simply visiting the building would be an experience in itself – guests will be able to stroll freely through the multi-level main building, reaching its summit, from where they can continue their walk along a 400-meter promenade surrounding the complex. The building will also feature three green patios, allowing natural light to reach even the artists’ backstage areas on level -1.
As part of the second phase of the project, two outbuildings in the northern part of the lot will also be renovated and connected to the main building, which houses a large concert hall. A chamber hall with approximately 400 seats will also be built, along with extensive facilities for artists and technical spaces: dressing rooms, rehearsal rooms, storage areas, a music library, and recording studios capable of broadcasting live concerts, etc. This space will be complemented by a garden open to the public, connected to a nearby park.
WARBUD has been appointed the general contractor for this phase of the project; in previous years, the company was responsible, among others, for the construction of the Podlasie Opera and Philharmonic in Białystok, the headquarters of the Polish National Radio Symphony Orchestra in Katowice, Mieczysław Karłowicz Philharmonic in Szczecin, and the Museum of Modern Art in Warsaw. The project is funded by the Capital City of Warsaw and the Ministry of Culture and National Heritage.
